2006-09-24ocfs2: Remove i_generation from inode lock namesMark Fasheh
OCFS2 puts inode meta data in the "lock value block" provided by the DLM. Typically, i_generation is encoded in the lock name so that a deleted inode on and a new one in the same block don't share the same lvb. Unfortunately, that scheme means that the read in ocfs2_read_locked_inode() is potentially thrown away as soon as the meta data lock is taken - we cannot encode the lock name without first knowing i_generation, which requires a disk read. This patch encodes i_generation in the inode meta data lvb, and removes the value from the inode meta data lock name. This way, the read can be covered by a lock, and at the same time we can distinguish between an up to date and a stale LVB. This will help cold-cache stat(2) performance in particular. Since this patch changes the protocol version, we take the opportunity to do a minor re-organization of two of the LVB fields. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-09-24ocfs2: Hook rest of the file system into dentry locking APIMark Fasheh
Actually replace the vote calls with the new dentry operations. Make any necessary adjustments to get the scheme to work. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

2006-06-29ocfs2: Compile-time disabling of ocfs2 debugging output.Joel Becker
Give gcc the chance to compile out the debug logging code in ocfs2. This saves some size at the expense of being able to debug the code. Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
2006-06-27[PATCH] spin/rwlock init cleanupsIngo Molnar
locking init cleanups: - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK() - convert rwlocks in a similar manner this patch was generated automatically. Motivation: - cleanliness - lockdep needs control of lock initialization, which the open-coded variants do not give - it's also useful for -rt and for lock debugging in general Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-03-01[PATCH] ocfs2: fix -Wformat warnings when building UML on x86-64Jeff Mahoney
The check to determine which format string is appopriate for u64 and friends works in most cases, but UML on x86_64 doesn't define CONFIG_X86_64, so it results in screen fulls of compile-time warnings. This patch fixes it to handle that case. fs/ocfs2/cluster/masklog.h | 2 +- 1 files changed, 1 insertion(+), 1 deletion(-) Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

2006-01-09[PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_semJes Sorensen
This patch converts the inode semaphore to a mutex. I have tested it on XFS and compiled as much as one can consider on an ia64. Anyway your luck with it might be different.
